The Express Media Server is a set of software modules that reside on the Application Server. During installation, you will have the option to choose either the Hardware Media Server or the Express Media Server. For details about the EMS, see the Express Media Server Requirements.

CUCM 8.0(3) is the only release that supports SIP Refers for multinode Cisco Unified MeetingPlace systems (WebEx-scheduling deployments). If you require this support, open a case with Cisco TAC against the Cisco Unified Communications Manager to obtain the latest Engineering Special (ES) or Service Update (SU) version of CUCM 8.0(3).

License Requirements

This release of Cisco Unified MeetingPlace uses host-based licensing. The system uses an audit mechanism to track the number of users who have created meetings and compare that to the number of licenses that are installed. An alarm is raised when the number of users who create meetings exceeds the number of licenses installed.

If you have no licenses installed the system will allow only a single meeting at a time.

Note: If you are completing a Cisco UCS installation under VMware, note that the Cisco Unified MeetingPlace system produces a randomly generated 12-digit "MAC address" that you will require for licensing. To obtain the MAC address, make sure that you install the Meeting Directors first. You can then obtain the randomly generated MAC address and register your license key.

Failover Requirements

To configure failover, you need two Application Servers with a high-speed network connection of 100Mpbs or better between them. Failover configuration requires the following:

When you configure the Application Server for the Express Media Server, both the primary and secondary failover Express Media Servers must have the same licenses and port distribution.

The active and standby Application Servers can be on different timezones, but the time must be synchronized between them. This is required to resolve conflicts when the same piece of data is modified simultaneously in both Application Servers.

To ensure that times are synchronized, we recommend that both Application Servers are synchronized to the same NTP server. If different NTP servers are used, make sure that these NTP servers are high-Stratum servers, that is, stratum-1 or stratum-2, to minimize the chance of an Application Server synchronizing to an inaccurate clock.

Note: Directory Service between two Application Servers is not supported in a failover deployment.

Network Requirements

This section lists the incoming and outgoing ports that are used by the various components of the Cisco Unified MeetingPlace Release 8.5 system. The information refers to Audio-only deployments.

Use these tables to make sure that your firewalls do not block access to Cisco Unified MeetingPlace from users or integrated systems, and to make sure that you do not block communication among the Cisco Unified MeetingPlace components and servers.

The ports that you do not need to expose to system administrators or end users are used for local communication between the Cisco Unified MeetingPlace elements or between Cisco Unified MeetingPlace and local services such as Cisco Unified Communications Manager. Such ports should be blocked in the DMZ or external firewall, but should not be blocked between internal components of the Cisco Unified MeetingPlace solution.

Integration Requirements

Note: The Cisco Unified MeetingPlace integrations for IBM Lotus Notes and Microsoft Outlook are only supported if your deployment is configured for MeetingPlace-scheduling or audio-only. Deployments configured for WebEx-scheduling use WebEx Productivity Tools.
